WATER-CLOSET FIXTURE.

Specification of Letters Patent.

Patented Mar. '7, 1916.

Application filed April 29, 1913. Serial No. 764,348.

To (ZZZ whom it may concern:

Be it known that I, ANDREAS VALDEMAR CHRISTENSEN, plumber, subject of the Kingdom of Denmark, residing at Odense, Denmark, have invented certain new and useful Improvements in VVater-Closet Fixtures, of which the following is a specification.

The invention relates to improvements in water closet fixtures.

The object of the present invention is to improve the construction of water closet fixtures and to provide a simple, efficient, and comparatively inexpensive water closet fixture equipped with a container located below the frost line and into which the water from the pipe connections of the flush tank is completely drained after the said tank has been flushed, whereby the exposed parts of the fixture above the frost line will be free from frost and ice, and effectually prevented from becoming inoperative through freezing.

A further object of the invention is to provide a water closet fixture of this character, equipped with means for creating a partial vacuum within the container, and for drawing off a portion of the water contained within the same While the flush tank is being filled, whereby the excess of water will be rapidly drained into the container after the tank has been flushed. The details of the invention, and especially the way in which the water pipe is filled and emptied, will appear from the following specification and are furthermore illustrated by the accompanying drawings, which show one form of construction and in which:

Figure 1 is a side elevation partly in section of a water closet fixture constructed in accordance with this invention; Fig, 2 is an enlarged sectional" view of the drain tank or container; Fig. 3 is a detail sectional view showing the construction of the auto matic ball valves.

For the sake of simplicity, the water-pipe is sholwn only connected with a single flushingtan In the accompanying drawing 1 is the flushing-tank, 2 is the outer part of the siphon, 3 is a fioat disposed on and secured to the latter or the said float 3 may be connected therewith by any suitable means, 4 is the handle, 5 is the lever, and 6 is the waterpipe. Inside the water-pipe and throughout its entire length there is disposed a rod 7, which, for each floor or each water-closet (flushing tank), is provided with a suitable engaging-member, for instance, the U- shaped member 8 shown in the drawing. On the pipe 6 there are disposed, at corresponding points, a casing 9 which is provided with tight bearings for the axle 10 of the lever 5, which axle actuates the member 8, for instance by means of'a cam or crank-arm 11 disposed between its branches. Down below (at a frost-free depth) the pipe tligends in a socket 12 on the cover ofia tank nected with a pipe 14, whose upper end is inserted in the socket 12, and which is passed through a packing-box 15 in the cover of the tank. The pipe 14 is, at its lower end, connected with an injector cone 16, whose nozzle 17 has an elongation 18, which at its lower end is provided with the aforesaid main-valve 19. The valve-casing 20 of this valve, which is provided with guides for the members 17 and 18, is secured to the bottom of the tank, or chamber, 13, and at its lower end it is connected with the main waterpipe 21.

WVhen the valve 19 is open, as shown in the drawing, the water from the pipe 21 will run through holes 22 into the injector 18, 17, and through the injector-cone 16 up into the pipe 14, at the top of which it runs out through holes 23 and then rises up in the water-pipe 6. As a result of the effect of the injector, a part of the water remaining in the closed tank 13 will be sucked up through the pipes 14 and 6, and the air above the water in the tank 13 will be rare The rod 7 is, at its lower end confied. The significance of this will appear the position shown in the drawing, thereby causing the cam 11 on the levers axle 10 to actuate the lower branch of the member 8, thus forcing the rod 7, together with the parts 14, 16, 17 18 and 19 connected therewith, downward a suitable distance; At the same time a valve 26, in a connection be tween the water-pipe 6 and the tank 1, is opened by means of rods 24 and 25, so that the water can run into the tank 1. When the water has risen to a certain height in the tank 1, the float 3 is lifted, and thereby also the siphon-member 2, and when the siphon acts, the tank is emptied.

The siphon-member 2 or the float 3, carries a rod 27, which is passed through the cover of the tank and at its top end has a suitable head 28. The said latch 29, which catches onto a projection 30 on the lever 5,.

also has a jointed projection, or pawl, 31, which can be passed by the head 28 on its upward stroke but is pulled down by the head on its downward stroke. This latter movement is made as soon as the siphon has acted, the members 2, 3, 27 and 28 then falling again. 3 The latch 29 which, together with the projection or pawl 31 has the form of an angle-lever, will then be turned and released from the projection 30 on the lever 5, so that the latter is liberated and returns to its normal position, for instance under the influence of a spring 32. Thereby the valve 26 is closed, and the cam 11 is brought into the position 11 shown by the dotted lines. It isobvious that this normal position does not prevent the levers and thereby the rod 7, 8, together with their appertaining members, in the water-closets on the floors above and below the water-closet here in question from functioning in the aforesaid manner. In other words, thisinvention can be made use of in an optional number of waterclosets situated immediately above one another which can all be flushed in the usual manner independently of one another. When the cam 11 is turned back into the position 11, a spring 33, or the like, which may be disposed at the top end of the rod 7, will with the assistance of the water pressure from the supply close the valve 19, and

the water in the pipe 6 will run back into the tank 13, where, as before mentioned, there is a low pressure. Besides the aforesaid holes 23, the pipe 1 1 may also have other, somewhat lower situated holes 34 which, when the valve 19 is closed, are lifted up to level with the lower edge of the socket 12, so that even the socket 12 is emptied of water.

In order that the tank 1 may be completely emptied, there may be disposed between its bottom and the water-pipe 6 a connecting pipe 35with an automatic valve, for instance a ball-valve, 36 which closes the connection when there is an excess of pressure in the pipe 6 and opens it when the pressure falls. Fig. 3 of the drawings shows the operation of the valve, representing the same in its upper position when it is open. In its lower position the ball rests on the ribs 36 The spring 33 may be disposed in a special prolongation 37 of the top end of the pipe 6, and from there a pipe 38 may lead to the upper flushing-tank or its flushing-pipe, so that the pipe 6 is above in open connection with the atmosphere. The prolongation 27 of the pipe 6 is provided at its upper end with an automatic valve similar to the valve 36, for closing the passage through the prolongation to prevent the water from flowing through the pipe 33 when the valve 19 is open. The construction of this valve is shown in Fig. 3, it being identical with the valve 36.

Instead of closing the tank 13 tightly and producing a sub-pressure in it by means of theinjector 16, 17, the tank 13 may also be furnished with a regulated air-connection (cock, valve, or the like), which is closed when the main valve19 (and the valve or one of the valves 26) is opened, and is kept closed as'long as the flushing" lasts, but is opened as soon as the flushing is finished. Then the water in the pipe 6 will also be able freely to run down into the tank 13. The regulating of this air-connection may be accomplished in a suitable manner from the rod 7, the lever 5, or the like. The rod 7,8, or a similar, maneuvering member, does not need to be disposed inside the pipe 6, but may be disposed along the side of it or entirely independent of it.
